三峡电力市场优化调度系统及算法

介绍了用于三峡电力市场优化调度的数学模型，算法和部分应用结果。三峡－葛洲坝大型梯级水电站与三大区，八省（市）的电力系统相连，模型考虑了各种水力和电力约束（水头变化，回水影响，航运约束等要求），采用了新的可加速收敛的夹逼可行方向法和可以从不可行初始解处开始计算的广义out-of-kilter算法，并利用了大型线性规划问题可分的特性，使该超大型的复杂非线性规划问题变得容易求解。文中用此模型和算法研究了三峡电力市场面临的多种决策问题，结果表明该软件系统在确定分电比例和市场价格以及制定优化运行方式等方面有重要意义。

ALGORITHM AND APPLICATION OF OPTIMAL DISPATCHING FOR THREE GORGES ELECTRICITY MARKET

This paper presents the model and algorithms of optimal dispatching for the Three Gorges electricity market, and its applications. The large cascade hydropower system in this reach of Yangtze River, consisting of the Three Gorges Hydropower Plant and the Gezhouba Hydropower Plant, is connected with the power systems of three large areas and eight provinces. Various electric and hydraulic constraints are considered. The new feasible direction algorithms, which can fast converge, and a nonlinear minimum network flow algorithm based on out of kilter method, which can begin with non feasible solution, are presented. And the separable nature of large linear programming problem is used. Thus the large scale nonlinear optimization problem becomes easy to solve. Various operation problems that the Three Gorges electricity market is facing are researched. The significance of the software for optimal dispatching, pricing and distribution of electric energy is proved.
